The scale of the image that maps "Figure a" to "Figure b" is:

3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."
The final result will be:


I don’t know how to solve it on a graphing calculator but i can solve x for you♀️.
Formula: 2(l*b+b*h+h*l)
2(3*5+5*7+7*3)
2(15+35+21)
2(71)
SA= 142
Answer:
a. 1 3/4 + 2 1/4 = 4
b. 7/3 or 2 1/3 = 5 2/3 - 3 1/3
c. 8 5/6 - 3 4/6 = 5 1/6
